Nicole Kidman is one Hollywood star who it seems always looks impossibly glamorous but the Moulin Rouge actress's latest look won't be catching on anytime soon.

The 46-year-old looked dishevelled and coated in streaky fake tan as she donned a large straw hat - while wearing a big white fluffy dressing gown, usually reserved for lounging around in posh hotels - on the set of her new film Strangerland.

Nicole was barely recognisable, with her famous red hair dyed brown for her part as Catherine Parker - the mother of two children who go missing in the outback.

And her normally pale skin appears darkened and marked in the pics for the role, perhaps from filming scenes showing her searching in the outback or perhaps from a brush with a bottle of fake tan.

The American-born Aussie first arrived back in Sydney from the US last month, before making her way to the tiny 2,000-people town of Canowindra, in the central west of New South Wales, to shoot some of the flick.

The movie is also being filmed in the isolated mining city of Broken Hill and Sydney suburb Hammondville, where the down to earth star posed for snaps outside of her dressing room trailer with fans last week.

Schoolgirl Harmony Barry, 17, was there with her friends and family, and told MailOnline Nicole was delightful and more than happy meet and greet her excited fans.

'The whole time she had a nice smile on her face and was really lovely to everyone which was so nice.'

'She was in the makeup van - so I was just standing out the front waiting for her to come out.'

'When she came out she said "hi" to everyone...she did say I'm on a tight schedule but even after that she hung around and took photos with everyone that was there.'

Nicole will star alongside Joseph Fiennes (Shakespeare in Love), who will play her husband in the movie, and Hugo Weaving (The Matrix), who will play the policeman leading the investigation in the movie.

Meanwhile, in a pre-recorded episode of The Queen Latifah Show on Monday night, Nicole stunned viewers in a classy fitted red dress as she discussed how her marriage to Keith Urban is 'healing'.

The immaculately dressed star confessed: 'You kind of move into each other and discover and heal a lot of things in each other too. It's very healing when gently done'.

She also spoke about her great life living in country music capital Nashville with the New Zealand-Australian singer.

Nicole this week had to skip Keith's glitzy awards performance at the 49th Annual Academy Of Country Music Awards in Las Vegas because of her filming commitments for the indie film Strangerland.
